I see that almost everyone is facing forward in the photos. I can manage this by pressing “C”, and then maybe take a screenshot with hamburger => Scene menu. Maybe there is a better way, but probably a little unintuitive.

Particularly, I find commenting on someone else’s photo, and adding comments, confusing. Especially when there are already multiple comments.
For walking and turning camera, I tried plugging in a game controller (X-box style), but it doesn’t have a good experience as using a keyboard. (Which not only arrow keys, but also alphabetic ones with no…[Read more]

I am not very used to the controls yet so far. Upload and add/edit text doesn’t give enough good experience.
1) Did uploading your picture and presenting it in a shared virtual space feel different from sharing it in a classroom or discussion board?
A little, but it’s also because of too much 3-D, and user experience. Somewhat similar to MMORPG…[Read more]

I asked Gemini about extended reality (XR), and it says that strong presence, high plausibility, and effective design are important, probably regardless of realism. (But AI could be sycophantic.)
Maybe not exactly how many senses are manipulated, but how convincing in the end — how good is the consequence, how much you can control, how deep is…[Read more]

Not all VR apps are Cardboard enabled. And many of those that are have ads that are usually not VR enabled. To my understanding, non-VR apps work with VR headset too, but would feel like watching in a theater, like Cardboard’s demo.

The time may be calculated after startup by crystal frequency (High Frequency Clock), just no point of reference to calculate dates. Not sure how reliable is it internally. Online connection may be helpful for calibration.

Depending on the API call, the code could do anything. It doesn’t need to be a fixed interval, but rather a slightly more complicated logic, like above a value combined (software sensor?).
Only that I am not sure how difficult to update the program in the Arduino, versus update the server.

After than, I took the sensor device to another place, and broke the sensor in the process.

Glucose measurements are mentioned in related papers. For continuous monitoring, the cost could hinge on that.
It measures instead on drip bottle weight getting emptied, which is already about management of repeated hypoglycemia in home settings??

The study focuses on an interesting sensor device, wearable health-monitoring systems (WHMS), which can be helpful in selected population, such as those who need cardiac monitoring. Further studies may identify usefulness in other populations, such as elderly with fall risks and hypo/hyperthermia.
Furthermore, it focuses on comfort and…[Read more]

My understanding is greater London is like Thailand’s area around Bangkok (ปริมณฑล), that is, it doesn’t include City of London. However, greater London + city of London = London region, as one of the nine regions of England.
This center of the last image is white, because it is the real city of London.
In short, 32 boroughs are not city of London.

Thank you very much for sharing. It is always nice to see more code.
However, this makes it confusing with Local Moran’s I
– A positive value for Ii indicates that the unit is surrounded by units with similar values.

To add more the confusion, there seems to be multiple kinds of local spatial statistic G, as seen in R language help for

As far as I realized, minimum of

andLDNSuicides.shp
are required to learn this example.However, as far as I have Googled, I failed to find this dataset online (in year 2021), as well as the associated documentations (what are the units of E, y, x1, x2; and what do the numbers mean?).

– Within 2005 to 2014, the suicide rates in Thailand had been shockingly numbered at around 3,600 to 4,000 people every year. Also, the suicide rates had generally been rising since 2011, at more than 6 suicides per 100,000 inhabitants.
